CPU Limit In CentOS
A few years ago, I vaguely recall some issue with RHEL needing a special license or something like that, if you had more than a certain amount of CPU’s or a certain amount of RAM.
Does CentOS work fine for 2 CPU’s, 16 cores, 32 threads, and 256 G of ram?
CentOS6 specifically.

According to these, CentOS 6 and rhel 6 are limited to 16G of ram. But I currently have a rhel6 system with 128G, so … Don’t know what to think about that…

This affects only 32bit installations. 64bit installation supports up to
64TB.

Gaah! Sorry. I looked at x86 and not x86_64. So that answers that.
But the question still stands – In the past, I think there was a limitation of RHEL ES, and if you went over that, you needed RHEL AS.
As far as I can tell, there is no such distinction (and never has been) in CentOS. For that matter, as I browse redhat.com right now, it’s not clear that they have any such distinction anymore either.
I have CentOS 6 box with 4 CPUs, 64 CPU cores and 512 GB of RAM… for about two years. Runs great.

BUT on C6 for an AMD processor (x86_64) = 3TB/64TB RAM, so I am not complaining even though I can not afford to buy 3 TB of RAM and a suitable motherboard :-)
